Brian,

AFAIK the delay is caused by the way the X100P detects ringing.. If you 
are using digital lines (ISDN) then there is a signal to tell the device 
connected to the line that it is ringing but with an analog line this is 
not the case..

So the X100P basically looks for the "swings" on the line that indicate 
that it is ringing, it goes through about 3 of them before it answers to 
avoid "phantom" calls which used to happen a lot and were very 
irritating especially in the middle of the night.. So what you are 
experiencing is normal..

Later..
